What this tool does
About the image alt text auditor
Paste HTML to inventory image alternatives and flag patterns for manual review. Empty alt text can be correct for decorative images, so context remains decisive.
How to use it
- Paste the page HTML.
- Read the inventory: every image with its src and alt value.
- Review the flags — missing, empty, duplicated, filename-like and over-long alts each get one.
- Rewrite the flagged alts to describe function or content; leave genuinely decorative images with alt="".
Useful for
- Audit a template’s images after an accessibility complaint or Lighthouse flag.
- Find the IMG_4032.jpg-style alt text a bulk import scattered across a site.
- Prepare an image-SEO pass by inventorying what every img on the page declares.
Straight answers
Image Alt Text Auditor FAQ
Is empty alt text always wrong?
No — alt="" is the correct marking for decorative images, telling screen readers to skip them. The wrong states are a missing attribute or a filename; the auditor separates all three.
Does alt text help image SEO?
Yes: it is a primary relevance signal for image search and the fallback text everywhere else. Describe the image for a person; the search benefit follows.
